New southwestern Compositae. 
By Epwarp L: GREENE. 
The following species, hitherto. undescribed, occur in considera- 
ble fascicles of miscellaneous Compositae collected in various parts 
of New Mexico and Arizona by Mr. E. O. Wooton, and submitted 
to me for determination : : 
v COLEOSANTHUS WOOTONI. 
Pale with a short cinereous pubescence; leaves coriaceous, 
lanceolate, serrate, 2 inches long, longer than the internodes, 
Spreading or recurved, short-petioled or subsessile; cymes sub- 
sessile in the axils of all the upper leaves and terminal; in- 
volucres about five lines high, little imbricated, the short outer 
bracts ovate, or oblong-ovate, the others oblong-linear, all finely 
striate and less pubescent than the leaves: achenes pubescent ; 
pappus very fine, barely scabrous. 
Organ Mountains, Dona Ana Co., New Mexico, Sept., 1892. 
* ERIGERON CONDENSATUS (Eaton).

Perennial, subacaulescent, the subscapiform merely bracted 
monocephalous tufted stems only a few inches high; the densely 
tufted spatulate but very narrow leaves an inch long ; bracts of the 
hemispherical involucre subequal, hispidulous ; rays numerous, 
rather broad, white or pinkish; pappus of few and slender bar- 
bellulate bristles and an outer series of oblong paleae, these toothed 
or lacerate at the rather obtuse summit. 
Species not uncommon in southern Nevada and adjacent Ari- 
zona, wearing much more the aspect of £. pumilus than of E. con- 
cinmnus ; very distinct from either in the character of its pappus. 
Mr. Wooten’s fine specimens are from the base of Mt. San Fran- 
cisco, Arizona. : 
v MACHAERANTHERA LINEARIS. 
Perennial, the stem 3 to 5 feet high, puberulent but not vis- 
cid, the branches leafy below, narrowly paniculate above ; leaves 
linear, or the lowest lance-linear, 3 or 4 inches long, glabrous, 
3-nerved, remotely and sharply dentate and scabrous-ciliolate; — _ 
heads of the somewhat thyrsoid panicle numerous ; | broadly
